Hi Buggy,
My H has far from come out of his tunnel, but it is clear that he has some wounds. In his case, he felt that his mum was somewhat resentful at having a family rather than a career, because she was so good at school. Then, she had to cope with 4 kids on her own after his dad was killed. I think she became very critical/ controlling, less affectionate. Then he was sent to a very strict boarding school at age 9, and didn't see he family for months. So he became very introverted in response, and autonomous, with control (and self control) as major issues. He probably failed to develop interpersonal relationships as much, and has definately worn a mask of duty and perfection. He has worked 7 days a week for the past 10 years, and much of the previous 12. He only relaxes a week into his holiday.
He projected that perfection on me when we first met (I was his angel from heaven), then became progressively furious that we were in his space, and not perfect (just human). He then projected all his fears onto me. His shadow, as far as I can see, is to lose control, stop trying to be perfect, and have a break from doing his duty. It is to accept that he is sometimes fearful, not always perfect, and to live.
